Re: RCT remaining tasks

Oh, I have found a simplification in the ECCA design ... the direction switching does not need to insert glider before the direction semisnark. It is sufficient to make glider stopper on the line to prevent first of the G0 gliders to reach the semisnark, as the first glider is the decrement glider,...

Re: Spacefiller Recipe Working Thread

Good point. I had wondered about that, but had just assumed that there was some subtle crossing stream somewhere that would prevent all eight sets of longboats from being moved in. But they do all adjust inward just fine, up to 293 full diagonals: You could make the script move every longboat in as...

Re: Banks-V when

Since Banks-3 is the state reduction over Banks-2, I bet that Banks-5 will have 1 state less than Banks-4: Serizawa's rule has 3 states, rotate4reflect symmetry, the von Neumann neighbourhood, and is capable of universal computation and construction: https://onlinelibrary.wiley.com/doi/abs/10.1002/...

That seems like a lot of SLs, is there any way to check if it’s optimal? It's almost certainly not optimal.

Re: RCT remaining tasks

The Pattern seed would wait alone roughly 8 aeons more for the glider from the last cordership destruction on FNW. I like it more this way, the seed of destruction has to sent only the signal destroying the (far) arm block. Rather to sending a LWSS to activate the pattern. How does the ATBC seed ge...

So this is end of my hard work and I hope someone else will compute the seed of destruction. Excellent work! I'll work on the seed of destruction now.

This is just to say that there is another way to get a constant-time read with a 1D tape of still-lifes: use two stacks instead of a tape (with the top of the stack nearest to the computer) and design spaceship salvos which push/pull the tape of still-lifes. Probably the cheapest technology to use h...

Re: Extreme compression construction arm

Nice the pslmake uses 16 glider signatures (2 colors 8 phases in them) to allow filtering recipes not doable by DBCA/ECCA, unfortunately (seems to me) the database is not processed to support recipes with such restricted phases. (A lot of p2 recipes could be discarded by a pessimistic reasoning.) Y...
